IPv6 routing protocols

Like IPv4, IPv6 also supports routing protocols that enable routers to exchange information about connected networks. IPv6 routing protocols can be internal (RIPng, EIGRP for IPv6…) and external (BGP).

As with IPv4, IPv6 routing protocols can be distance vector and link-state. An example of a distance vector protocol is RIPng with hop count as the metric. An example of a link-state routing protocol is OSPF with cost as the metric.
